DlRT-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 320,055, dated June 16,1885.

(X0 model.)

To all whom it may concern:

Be it known that we, FRANK DUsY and Aswan MCOALL, of the city of Selina,county of Fresno, State of California, have invented an Improvement in aDirt-Scraper; and we hereby declare the following to be a full, clear,and exact description of the same.

Our invention relates to certain improvements in dirt-scrapers; and itconsists of a bowl, the front edge of which is adapted to scrape up thedirt and deposit it within the bowl, ends to the bowl having the frontformed into arc-shaped runners upon which the device may be tilted anddrawn along, connectinglinks by which the end pieces are united to theaxle of a pair of wheels situated in front, and chains connecting thesame axle with the central portion of the arcs before mentioned, so asto provide adjustable draft for the scraper when turned upon these arcs,and a jointed or divided axle for the wheels, by which the draft, whenthree or more horses are used, may be equalized, and in certain detailsof construction, all of which will be more fully described by referenceto the accompanying drawings, in which Figure l is a perspective view ofa scraper. Fig. 2 is an end section, showing the scraper in position toload itself when drawn along. Fig. 3 is an end view, showing the scraperin position to discharge gradually. Fig. 4 is a view showing the scraperin position to discharge the load at a single point. Fig. 5 is a planview showing a modification of the axle.

This invention is especially applicable to what are known asdump-scrapers and to what are known as lnick-scrapers. In thedump-scrapers power of the horses is applied to drag the scoop-shapedscraper filled with dirt to its destination, and then, partly aided bythe driver, the scraper is upset, leaving its load at a single point. Inthe buck-scraper power is applied to drag a vertically-placed board orplank along the ground, so that it scrapes dirt in front of it to itsdestination, where it upsets so as to leave the load.

In our invention A represents the bowl or scoop portion of the scraper,which is of the proper shape to hold the dirt, and is provided with ahandle or handles, 0, extending backward from the rear portion. Thefront edge is of such shape and material that when in the properposition, as shown in Fig. 2, the scraper will take up the dirt as it isdrawn along the ground until it is filled.

B B are the ends of the scraper. The ends have their front portioncurved, as shown at H, into the form of a circular segment, the archedportion of which projects beyond the front or cutting edge of thescraper, and its lower portion is slightly above the level of the edge,so as not to interfere with its cutting the dirt and loading itself whendrawn along. Vhen the scraper is filled with dirt, and it is desired todischarge by raising up the handles, it will be seen that the scraperwill turn up on the curved runners ll, more or less, so as to dischargeits load, and to hold it in the proper position when it is turned up todis charge its load. It is connected with the axle D of the pair ofwheels E, as follows:

F F are links, the rear ends of which have pivot-bolts securing them tothe ends B at a point near their center, while the front ends of theselinks are connected with the axle D by a sort of clevis or fork, asshown. The front ends of these rods are closer together where they areattached to the axle D than at the rear ends, where they are attached tothe ends of the scraper, and as the horses are. attached to the axle bydouble-trees at points near the ends, this construction will allow onehorse or a pair to start considerably before the others withoutmaterially changing the position of the scraper, thus keeping it equallybehind the team. which is an important point in loading or unloading.

G G are chains extending from the axles to points near the center of thecircular arcs H, which are formed at the front of the scraper ends, asbefore described. These chains are attached to hooks upon the axle, andmay be taken up or let out a link or two whenever desired.

The operation of the scraper will then be as follows: Horses beingattached to it, and the scraper being held in position shown in Fig. 2,the links F connect it with the axle and act to draw it along when thehorses are in motion until it is loaded with dirt, the chains G being inthe meantime slack. \Vhen the scraper has reached its destination, if itis desired to unload it gradually, it is done by shortening up thechains, as shown in Fig.3.

ICO

2 szoess The handle 0 is then turned up, thus tilting the scraper untilit rides on the curved runners H, and the length of the chain Gdetermines the position in which it will be drawn.

If the chain is short, as shown in Fig. 3, the edge of the scraperwillbelifted a little above the ground, and the dirt will spill outgradually and be spread over considerable space, and if it is desired todump it all at once the chain is let out, as shown in Fig. 4, when thescraper will be drawn farther over, and the draft then comes upon thechain, drawing it upon the runners, the edge of the scraper being sohigh above the ground that the dirt will be discharged at once. WVhilethe scraper is being drawn upon the runners by the chains, the rods orlinks F, which are flexibly con nected between the axle and the scraperends, serve as braces to prevent its being turned entirely over upontheteam, and after its load is discharged it may again be turned downinto place for another load.

When another team is to be attached, as in some cases, at or near thecenter of the axle D, the axle may be made in two parts, and a curvedyoke, I, may be united to them by means of links or flexible joints atJ. If it is desired to support the inner ends of the axles at thispoint, a wheel, K may be supported upon an axle, L, between the sides ofthe curved yoke I, as shown. In this case another double-tree, M, wouldbe connected with the front of the yoke, having the usual single treesfor the attachment of another pair of horses.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. In a scraper, the scoop or bowl having the ends provided with curvedrunners on the front portion, wheels and axle to which the draft-animalsare attached, links flexibly connected with the axle and extending tothe middle of thescraper ends, and chains extending from the axle to thecurved portion of the runners, as herein described.

2. In a scraper, the scoop or bowl having ends provided with curvedrunners at the front, said ends being flexibly connected by links withan axle mounted upon wheels to which draft-animals are connected, andflexible chains adjustable in length extending from the curved runnersto the axle, whereby the amount of tilt given the scraper maybe'regulated, as described.

3. In combination with the scraper having the ends with curved runners,as shown, the connected chains extending from the runners to the axle ofthe draft-wheels, and the links or rods flexibly connected with the axleat points nearer to each other than the ends of the scraper to whichtheir opposite ends are connected, substantially as herein described.

4. In a scraper, a wheel-axle to which a scoop or bowl is attached, asshown, said axle being divided in the center and having connecting-yokeI flexibly attached to its adjacent ends, and a means for attaching thedraft-animals thereto, substantially as herein described.

5. In a scraper, a wheelaxle having a scoop or bowl connected thereto,as shown, said axle being divided in the center, having its adjacentends connectcd by a yoke, I, and a supporting-wheel, K, journaled tosaid yoke, to gether with a means for attaching draft-ant malsthercto,substantiall y as herein described.

In witness whereof we have hereunto set our hands.
